National Ventilation 497 Condensation Trap with Overflow 100 mm/4 Inch
Condensation Trap 100-110mm with Overflow Connection. Fits either 100mm I.D. Pipe or 110mm O.D. Pipe
When a ventilation duct is installed in an unheated area, such as a cold loft space, condensation can form on the inside of the duct. This moisture can run down the duct and create a potential hazard, such as dripping onto the electrical connections of a fan or cooker hood. A condensation trap can be used to prevent this problem occurring.
The trap is simply connected to the system as part of the vertical duct run and an internal gutter within the trap collects the moisture and then drains it out through a standard overflow-pipe to the outside. This ensures that the moisture cannot enter a potentially hazardous area. The condensation trap should be installed as low as possible, whilst still high enough to maintain a fall on the overflow-pipe.
